摘要:
A new method for extinguishing fire is provided, characterized in that a pyrotechnic agent is used as a heat source (energy) and a power source (driving gas); during use, the pyrotechnic agent is ignited, and the high temperature generated by the combustion of the pyrotechnic agent is utilized to make a fire extinguishing composition produce a large amount of fire extinguishing substance, which is sprayed out together with the pyrotechnic agent, so as to achieve the purpose of extinguishing a fire. As compared with conventional aerosol fire extinguishing systems, gas fire extinguishing systems and water-based fire extinguishing systems, the fire extinguishing method of the present invention is more efficient and safer.
摘要:
The present invention relates to a novel aging-resistant aerosol generating agent and preparation method thereof. The aging-resistant aerosol generating agent in the present invention comprises oxidizer, reducer and bonding agent, wherein the oxidizer is potassium nitrate, the bonding agent is phenolic resin, and the reducer is melamine; the weight percentages of the three constituents are: potassium nitrate: 60˜80%, phenolic resin: 8˜15%, and melamine: the rest. In the preparation process, phenolic resin is dissolved in ethanol to give phenolic resin solution at concentration by 40˜50 wt %; the oxidizer and reducer are pulverized, mixed, and then the phenolic resin solution is added to the mixed powder; next, the mixture is agitated, pelletized, dried, and shaped by pressure molding. Compared to that in the prior art, the aerosol generating agent in the present invention has higher fire suppression efficiency and higher fire suppression rate, and greatly improved aging resistant performance.

The present invention relates to an aerosol fire suppression apparatus, comprising enclosure, internal bladder, aerosol generating agent and initiator, and cooling layer in a cellular structure or cooling layer formed by a cellular structure coupled with coolant in a spherical or irregular shape between a chemical agent and jet orifices. The cellular structure employed in the apparatus has a large heat exchange area, which can absorb a great deal of heat in a short time, and therefore delivers good cooling effect; the cellular structure is regular in shape, easy to assemble, and the assembled aerosol fire suppression apparatus is compact in size, space-saving, and easy to install; moreover, the cellular structure can support a catalyst material to remove toxic gases produced from the aerosol, such as nitrogen oxide and carbon monoxide, etc.
摘要:
A SRAM system which provides for reduced power consumption. The SRAM system utilizes an array of bit cells. Columns of bit cells in the array are partitioned into sections. Each section of bit cells shares a local bit line. A sector select circuit provides for precharging the local bit lines. The sector select circuit also includes a mux for connecting a local bit line to a global bit line. The sector select circuit includes a device for detecting when a sector select signal and a column select signal are present. When both of these signals are present the sector select circuit couples the local bit line with the global bit line, and disengages the precharging of the local bit line.
